Thepresent invention relates toshuttle chang ing looms operating withshifting shuttle boxes 52 and it is the general object of .the inventionto provide-an improved magazine for the reserve shuttles.

It is another object of my invention to provide a multi.-cell magazinebuilt up'of a plurality of substantially similar reserveshuttleunits-which y can conveniently be arranged in parallel order to delivershuttles Ito acarrier the path' of which is common to the units. Inthis-way I am enabled to increase the color capacity of the loom merelyby' adding additional units-and increasing" the length of travel of .thecarrier.

In this connection it is a further objectof the invention to provideeach unit with a selector mounted on apart of the shuttle unit andarrange the-magazine so that escapement devices canbelocated between theunits.

Itis a still further object of my invention to provide simpleandefiicient means to control the trailing weft ends of the reserveshuttles.

" several-.units orv stacksare so arranged that the weft endscan be ledto athreadholder located to permit free movement of the shuttles of.any. stackwithout disturbing the weftends of any. other stack. Thethread slotsof the several stacks: are positioned to accommodate threadsextending :flOl'Il the shuttle delivery eyeswhichmay be located asinnon-automatic looms, that is, with the shuttle eyes pointing-towardtheselvage when the shuttles areon the drop boxend of the v loom.Thisrelationrequires the shuttle eyes to beat the outerend of theshuttles when the lattenareat'the magazine end of the loom, and thisability to operate the automatic box loom with the shuttle eye locatedas on-the non-automatic 40' loom isa: novel and efficient feature of myinvention.

With these and other objects in view'which will appear as thedescription proceeds, my invention resides in the combination andarrangement of parts hereinafter described and set forth in the claims;

The magazine forming the. subjectimatter of this invention employs: aplurality of shuttle stor-' ingiandwreleasingunits, one for eachshifting 80f. shuttle box; There are-showntwo magazines 90 and 911eachzmadexof: three sections.

- the magazine.

Selector mechanism is employed to cause shuttle delivery to take placefrom the unit corresponding to the depleted weaving shuttle.Accordingly, each unit has a rock shaft 103 with control fingers 104fastened thereto, see Fig. 2. The rockshafts are mounted in lugs 105 onthe rearward sections 94 of the magazines, two fingers being used oneach rockshaft. The fingers of each rockshaft are movable under thecorresponding magazine to prevent delivery of the bottom shuttle.

The fingers are so moved that delivery can take place from but one unitat a time, namely, the one corresponding to the weaving shuttle to beejected. This control is exercised by the box motion not shown, by meansof a rod 112 which is reciprocated vertically by the shifting of theshuttle boxes, and is pivoted to an arm 113 fixed on the rear shaft 103,see Fig. 3. This last named shaft carries an arm 114 having a pin andslot connection with a similar arm 115 on the front shaft 103.

Thusthe shafts 103 are given equal but opposite angular movements eachtime the boxes shift and the delivery in turn is synchronously shiftedfrom one unit to the other. By reason of the slotted connections shown,the proper amount ofmotion for the fingers 104 can be derived from thebox motion. Each unit or shuttle cell is seen, therefore, to have itsown rock shaft 103 and selecting fingers.

Escapement devices are provided for each magazine to release the bottomshuttle and thereby permit selection by the fingers 104. These-escapement devices also act to prevent escape of more than one shuttleat a time from the selected unit. One such device is located at each endof each unit, and each escapement comprises a short vertical rock-shaft116 journaled in bearing 117 on brackets 118 secured to an end frame 96.Each tle to support a whole stack of shuttles the short arm will swingout of the path of descending shuttles, as shown in magazine 90, Fig. 4,but when the shafts 116 rock, the lower arm moves to release the bottomshuttle as shown at magazine 91, same figure. The lowest shuttle isthereby released so that it will be free to drop from The short arms actto prevent descent of the shuttles above the bottom one which has thusbeen delivered. As the arms return to their normal position,- theshuttle resting on the upper arms drops to the lower arms ready for thenext operation. These escapement devices, as stated, are located one ateach end of each unit and the arms of any pair are operatedsimultaneously, hence the shuttles are owered in perfectly horizontalrelation.

In order to transport a released shuttle to the previously describedconveyor, I provide a carrier 121, see. Fig. 5, having at each end asupporting portion 122. Each of said portions slides freely in a slot ortrack 123, Figs. Zand 3 formed on each magazine end frame. The tracksareinclin ed downwardly and rearwardly so that the path of the carrierwill intercept the arc of travel of the conveyor '77. By thisarrangement there will be rapid divergence of the respective paths ofthe carrier and conveyor, permitting the latter to pass the carrier andassume a position nearer the front of the loom, from which position theconveyor moves rearwardly to takethe shuttle from the carrier. Thecarrier is common to all the magazines, the tracks being long enough topermit the necessary travel of the carrier.

.From the foregoing it will be seen that I have provided a multicolormagazine built up of a plurality of similar units each of which suppliesa distinctive kind of shuttle. It will also be seen that each unitserves to space and brace the end plates of the magazine, and that therear section of a forward unit serves as a guard for the .weft ends ofthe unit behind it. Furthermore,

the front sections of each unit are so formed as to define a slot whichis in alignment with the delivery eyes of the shuttles, and these slotsand the eyes are placed so that the shuttle can op erate in the normalmanner found in non-automatic box looms, that is, with-the delivery eyespointing toward the selvage when the shuttles are in the shiftingshuttle boxes. Each unit carries its own selector, while the escapementdevices therefore are carried by the magazine frames which are held inspaced relation by the units so that said escapement devices areproperly related to the stored shuttles.

Having thus described my invention it will be seen that changes andmodifications may be made therein by those skilled in the art withoutdeparting from the spirit and scope of the invention and I do not wishto be limited to the details herein disclosed, but what I claim is:

1. In a multicolor shuttle changing loom, a pair of spaced end magazineforming plates, and a plurality of similar reserve shuttle magazinecells located between said plates, each cell being formed of a singlemember extending between the plates and two other members spaced fromeach other to define a thread slot and fixed with respect to the singlemember.

2. In a multicolor magazine for shuttle changing looms, a pair of spacedmagazine forming end frames, a plurality of shuttle storing unitsbetween the frames, each unit including a rear section section connectedto and spacing both end plates, each unit including a pair of frontsections having their adjacent ends spaced to'define a thread slot forthe weft ends of the stored shuttles, and a thread holder in front ofthe forward unit, the

weft ends of the shuttles in any unit extending over the rear section ofthe unit in front thereof to the thread holder. v

4. In a reserve shuttle magazine for shuttle changing looms, a pluralityof units each to contain a supply of reserve shuttles the threaddelivery eyes of which point away from the selvage of the cloth beingwoven, a pair of. front sections for each unit spaced to define a threadslot which
